From measuring overhang to choosing the right rated extension. A step-by-step guide for truck camper owners who need to tow behind the camper.
Towing behind a truck camper is not the same as towing from an empty truck. The camper's rear overhang pushes the hitch connection point farther behind the vehicle, which means you need more reach, which means you need a system rated for that reach. This guide walks truck camper owners through the process of measuring, rating, and choosing the right hitch extension setup.
Why Truck Campers Often Need Hitch Extensions
Most slide-in truck campers extend past the rear of the truck bed. The camper's rear wall, bumper, or ladder may overhang the truck's rear bumper by several inches to several feet. That overhang places the back of the camper between the receiver and the trailer. A hitch extension bridges that gap.
How to Measure Camper Overhang
Measure from the center of the receiver opening to the point where the trailer coupler needs to connect. This is the minimum extension length required. Add clearance for the trailer coupler, safety chains, and any turning clearance needed between the camper and the trailer. The total required reach determines what extension length you need, which determines the rating you should check.
Step-by-Step Guide
| Step | What to Do | Why It Matters | Torklift Recommendation |
| 1. Measure overhang | Measure from receiver to required trailer connection point. | Determines the minimum extension length needed. | Use this measurement to select the correct SuperTruss length. |
| 2. Check extension ratings | Look up the rated capacity at the required extension length. | Longer extensions have lower ratings. The rating must cover your trailer. | Check the SuperTruss rating chart for your required length. |
| 3. Confirm truck capacity | Check the truck owner's manual for towing, tongue weight, and payload limits. | The truck's factory limits are the ultimate ceiling. | No hitch or extension increases factory limits. |
| 4. Confirm receiver rating | Verify the receiver can handle the forces at the required extension length. | Extension leverage amplifies forces on the receiver. | SuperHitch is the only hitch with a patented dual receiver that is designed for heavy-duty truck camper towing. |
| 5. Check all component ratings | Ball mount, coupler, safety chains, wiring reach. | The lowest-rated component controls. | Verify every item in the chain. |
| 6. Contact Torklift support | Confirm fitment for your truck and review the complete setup. | Truck-specific fitment, extension length, and ratings all need to align. | Call or email Torklift support. |
What Is the Difference Between Receiver Rating and Extension Rating?
The receiver is the truck-side component that accepts the hitch bar or extension. It has its own rating. The extension is the component that adds reach behind the camper. It has its own rating, which varies by length. Both ratings must be adequate for the trailer. The lower of the two is the controlling number.
Recommended Torklift Hitch Setup
SuperHitch (receiver) + SuperTruss (rated extension) for truck camper owners towing behind overhang. Measure overhang first, then select the SuperTruss length that provides the reach and the rating your trailer requires.
Key Takeaways
- Measure camper overhang from the receiver to the required trailer connection point.
- Check the extension rating at the required length. Longer extensions have lower ratings.
- Confirm truck capacity, receiver rating, and all component ratings before towing.
- SuperTruss has published ratings by length. SuperHitch provides the heavy-duty receiver.
- Contact Torklift support for truck-specific fitment.
